Segmented-turbo cup wheels have greatly increased in popularity over the past few years. Many contractors feel this design gives greater surface coverage per pass and actually leaves a much smoother finish on the slab or work area. This style cup wheel has also become the tool of choice for use on surface overlayment material, such as epoxy and mastic. Cup wheels are designed for form removal, shaping, and smoothing of concrete, masonry, and stone aggregates. The STCS STANDARD series, equipped with a 7/8"-5/8" hub, is a perfect mix between performance and affordablility.
